Sweet 3D printed synth by #Repost@oskitone ・・・ This is the OKAY 2: a 3D-printed, analog, monophonic, square wave synthesizer based on the classic 555 timer IC chip. All lovingly designed by one very nice and cool person (me!) in San Francisco.
Available fully assembled or as a DIY electronics kit. You can even print the parts at home if you have a 3D printer!
